How we approach commercial & industrial rooflights in Altrincham
Thinking about commercial & industrial rooflights in Altrincham? The short answer: rooflights for warehouses, schools, offices and retail units. The longer answer depends on your roof, which is why we survey before we price.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Typical uses for commercial & industrial rooflights include industrial roofs with tired or fragile rooflight sheets.
Altrincham sits about 4 km from Sale and 7 km from Urmston, and we cover the whole WA14 postcode district and the roads in between.
What you can choose
- GRP or polycarbonate in-plane rooflight sheets
- Smoke and natural ventilation vents
- Mesh or grilles under fragile areas
- Modular glass rooflights
- Continuous barrel-vault rooflights
- Daylight that reduces daytime lighting
- Replacement of discoloured or fragile sheets
Things we check at survey
- Asbestos surveys may be needed on older roofs
- Non-fragility classification should be confirmed for new products
Regulations for commercial & industrial rooflights in Altrincham
For non-domestic buildings, planning depends on the building and its location; building regulations cover thermal performance and the fire classification of rooflights near boundaries. We confirm the route for your building before ordering.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Can you replace old warehouse rooflight sheets?
Yes. We match the roof profile, replace discoloured or damaged sheets and plan safe access while the building stays in use.
Are old rooflights a safety risk?
Older plastic rooflight sheets can become brittle. Anyone working on the roof must treat them as fragile unless proven otherwise.
Can rooflights double as smoke vents?
Some units are certified smoke ventilators. See our smoke-vent rooflights page.
Can you work alongside my builder in Altrincham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Altrincham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
